Why is food web very important in the ecosystem?
Accordingly, what is food web in ecosystem?
A food web (or food cycle) is the natural interconnection of food chains and a graphical representation (usually an image) of what-eats-what in an ecological community. Another name for food web is consumer-resource system. Some of the organic matter eaten by heterotrophs, such as sugars, provides energy.
One may also ask, what are the advantages of food web? (1) Members of higher trophic level can feed upon many organism of the lower trophic level of other food chains. (2) Presence of complex food web increases the stability of the ecosystem. (3) It has a trophic levels or populations of different speices.
Accordingly, what is a food chain and why is it important?
Food chains are very important for the survival of most species. When only one element is removed from the food chain it can result in extinction of a species in some cases. An example of a simple food chain would be: A plant grows using the sun's energy and nutrients from the soil. A rabbit eats the plant.
How is food web formed?
In their simplest form, food webs are made of food chains. Food chains show a direct transfer of energy between organisms. A chain might involve a mouse eating some seeds on the forest floor. Then, a snake comes along and eats the mouse.
